我尝试安装 cuda 9.0 而不是 cuda 9.2，因为 tensorflow 与它不兼容。我尝试了以下操作：
aims@aims:~/Downloads$ sudo dpkg -i "cuda-repo-ubuntu1604_9.0.176-1_amd64(1).deb"

如您所见，尽管我没有添加 Cuda 9.2，但它却无处不在。之前我添加了它，但在升级到 9.0 之前，我已清除了 cuda 9.2。但在安装时遇到问题。请帮帮我。
答案1
仓库http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/包含9.0、9.1和9.2。
运行时sudo apt install cuda它会自动选择最新版本。相反，你应该在安装过程中指定版本：
sudo apt install cuda-9-0
然后在安装后将其保留，以便将来运行时它不会尝试将其升级到该存储库中的最新版本sudo apt upgrade：
sudo apt hold cuda-9-0
我已经整理出在 16.04 中安装所有 3 个 CUDA 版本的答案https://askubuntu.com/a/1025949/231142
答案2
当你安装cuda-repo-ubuntu1604_9.0.176-1_amd64(1).deb文件时，它会将其存储库添加到/etc/apt/sources.list.d目录中。转到 sources.list.d 目录并删除它们。
sudo rm /etc/apt/sources.list.d/cuda*
sudo apt update
现在它不会更新到v9.2
